CARRIAG E-JAC K.

SPECIFICATION forming part of Letters Patent No. 451,686, dated May 5, 1891.

Application filed March 7, 1891.

To all whom it may concern:

Be it known that 1, CHARLES L. BELLAMY, acitizen of the United States, residing at Arlington, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Carriage-Jacks, of which the following is a specification.

My invention relates especially to carriagejacks or devices employed for removing wheels for the purpose of oiling the axle, &c.; and my present invention has for its purpose the provision of a simple form of construction of such a jack, the same being an improvement upon the construction shown in Letters Patent issued to me April 15, 1890, No. 425,728.

To attain the desired end my invention consists, essentially,in certain novel and useful combinations or arrangements of parts and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure 1 is a view in elevation of my improved carriage-jack. Fig. 2 is a face view of the wrench-jaws. Fig. 3 is a longitudinal central sectional view through the wrench-jaws. Fig. 4 is a cross-sectional View at line as so of Fig. 1. Fig. 5 is an enlarged axial sectional view through the extremity of the jack opposite to the handle.

Like letters of reference wherever they 00- cur indicate corresponding parts in all the figures.

A is the body of the jack, preferably made solid, and having radial ribs B at the sides thereof. At one extremity of the body is a manipulating-handle O, and at the opposite end is a perforation provided with both a right and a left hand female screw D, as particularly illustrated in Fig. 5. I have shown a ferrule E as forming the perforated extremity; but it is obvious that the end of the body A may be made solid and cored or bored instead of employing the ferrule.

E is a jaw fixed to the body of the jack and extending outward at a right angle thereto.

F is a movable jaw passing through a slot G in the body A, being movably mounted upon a pivot or pin H.

I is a spring resting in a cavity in the Serial No. 384,165. (No model.)

body A, andnormally forcing the movable jaw away from the fixed jaw.

J is a screw-threaded projection from the body A, formed therewith or affixed thereto at the side opposite to the wrench-jaws.

K is a conical nut arranged to engage with the.projection J, and against which the base of the pivoted jaw F impinges.

I have shown one movable jaw, but, if desired, both jaws might be pivoted in the body of the jack and each have a continuation of the base arranged to bear against the conical nut K.

' When the body of the jack is constructed as above described, it will be found to be very light, while possessing the requisite strength and rigidity. In using the device the wrench is set upon the axle-nuaand when the nut is removed it will be held in the wrench and cannot drop into the dirt, (to. By providing both the right and left hand screws at the end of the jack it may be screwed onto either end of the axle, from which the nut has been removed, and the wheel drawn longitudinally from the axle, while at the same time the wheel cannot go so faras to fall to the ground or let the side of the vehicle drop.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. A carriage-jack in which is comprised a rigid body constructed as set forth, bearing at one extremity a manipulating-handle and being provided at the other extremity with a perforation wherein is formed both a right and a left hand female screw and having a screw-threaded projection, a wrench-j aw fixed to the body of the device near the manipulating-handle, a movable jaw pivoted in close proximity to the fixed jaw, and a conical nut engaging with said screw-threaded projection from the body of the j aclqthe whole combined and arranged substantially as shown and described.

2. In a device of the character herein specified, a wrench having a movable jaw pivoted as set forth, in combination with a screwthreaded projection and a conical nut adapted and arranged to regulate the position of the movable jaw, substantially as shown and I have hereunto set my hand in the presence jack, of a fixed jaw, a movable jaw pivoted of two witnesses.

as set forth and having a projection at the back, a screw-tln'eaded proj eetion at the back of the body of the jack, and a conical nut CHARLES L. BELLAMY. 5 engaging with said screw-threaded projee- Witnesses:
